Why this card
The Guardian reported that scientists rediscovered the optical engineering behind ancient Roman color-changing glass. By 2038, this ancient nano-craft has been scaled up to create passive climate-control building materials. The picture shows a public pavilion using this structural glass to naturally filter harsh daylight into cool, beautiful shade without requiring electricity.
